Patent DE-2919324-A1 (DE)
Inventor: BRAUN ALBERT
IPC: C21C1/02
Filed: 1979-05-14
Abstract: The invention provides an agent for desulfurizing crude iron and steel melts, the desulfurizing agent being based on calcium carbide containing calcium oxide. The desulfurizing agent is produced by admixing a calcium carbide melt having up to 45 weight % of calcium oxide therein with an excess of 3 to 15 weight %, based on the CaO-content of more than 45 up to 80 weight % desired for the final product, of calcium oxide. The resulting mixture is allowed to solidify and cool down to temperatures of 350 DEG  to 450 DEG  C. Next, the solidified melt is precrushed to material with a size of less than 150 mm. Particles with a size of less than 4 mm are screened off and the remaining material is comminuted, with the exclusion of moisture, to material with a size of less than 10 mm.

Title: Synthesis of 2,6-Di:chloro-pyrazine - by chlorination of mono:chloro-pyrazine, using 2,6-di:chloro-pyrazine as solvent to minimise by=product formation
Inventor: GIOBBIO VINCENZO
IPC: C07D241/16
Filed: 1979-06-12
Abstract: Synthesis of 2,6-dichlorpyrazine (I) from monochloropyrazine (II) comprises (a) cold mixing (II) with (I) in such an amt. that the total concn. of (II) is 10-80%; (b) heating this mixt. to 70 degrees C; (c) leading gaseous Cl2 into the mixt. at 60-140 degrees C until the end of the reaction; and (d) isolating the (I). (I) is used in the synthesis of pharmaceutical and zootechnical sulphonamides, esp. 2-sulphanilidamide-6-chloropyrazine. (I) is used as the solvent; this eliminates the formation of any prods. from side reactions of the solvent e.g. in a previous process using organic solvents and only a little water, HCl quickly formed and reacted with the solvents to give chlorohydrate-contg. solids which blocked the appts. Conversion of (II) into (I) is complete, with the exception of small amts. of 2,3-dichloropyrazine (2-3%).

Title: Domestic water meter housing of steel reinforced concrete - has decomposable cavity former and metal fittings
Inventor: ANTON WALTER
IPC: G01F15/14
Filed: 1979-10-03
Abstract: The water meter housing (1) for domestic applications is designed for economy of manufacture. This is achieved by using reinforced concrete to make the walls of the housing. Threaded and other metal sections are either cast into the housing or subsequently inserted to enable the fitting of conducting pipes, screws for inspection purposes and/or observation windows. Manufacture is further simplified by the use of flat surfaces, esp. a square shaped housing. Steel mesh reinforcement is used. The metal fittings, pref. of brass, have rotation proofing and may be used to fill the casting mould with the concrete. The central cavity shaping mould may be of shaping sand hardened by water glass and softened by hot water. Alternatively, a thermally decomposable foam plastic former may be used.

IPC: B05C3/04
Filed: 1980-01-31
Abstract: Steel members for reinforced concrete construction are coated with a thermoplastic material to prevent corrosion. A conveyor (1) takes the steel parts (2) from the dipping tank (4) to a special turning device (8). When the parts are withdrawn from the dipping tank, a thread (13) of coating material forms at the end of the steel parts. This is then spread around the edge by the turning device (8). The conveyor (1) then takes the components to tank (12) where the coating is set by immersion in cold water. A specially thick bead of protective coating is formed around the vulnerable bottom edges.

Title: Hydraulic brake for motorcycle - has two pressure control valves for balanced brake effect
Inventor: LUEPERTZ H-H DIPL ING DR
IPC: B60T8/18
Filed: 1980-03-22
Abstract: The balance control is for hydraulic brakes for a motorcycle. It has the master brake cylinder (10) linked to the front and rear brakes by separate pressure control valves. The valves operate without restriction at the onset of braking, with the front brake pressure modulated before the rear brake pressure, when the foot brake is operated. The characteristics of both valves are linked so that the sequential modulation of the brakes provides a balanced brake control. If the handbrake is operated at the same time, the sequence is modified to take account of the additional braking on the front wheel. The brakes are designed to provide a balanced control even with panic braking.

Patent DE-3019810-A1 (DE)
Title: Flowing medium heating process - forces combustion products downwards through sloping pipe against which medium flows upwards
Inventor: BLACK ROBERT BEAUREGARD
IPC: F23K5/00
Filed: 1980-05-23
Abstract: The process heats a flowing medium using a heat-exchange pipe, one of whose ends is higher than the other. An upwards current of the medium is generated, in contact with the outside of the pipe, while the hot products of the combustion of gaseous fuel and air are forced downwards through the pipe. Flow speeds and temps. are such that the combustion products are cooled below thier dew point before leaving the pipe. The process can be used to heat water, the combustion products being forced through the pipe by a fan. A shutter at the pipe outlet opens only when the fan is running.
Patent DE-3020191-A1 (DE)
Title: Water flow control system through heat exchanger - varies circulating pump speed dependent on heat available
Inventor: ASSBECK FRANZ DIPL ING
IPC: F24D12/02
Filed: 1980-05-28
Abstract: The system controls the rate of water flow through a heat exchanger, by varying the speed of a water-circulating pump, so as to heat as much water as is possible to the desired temperature, using combustion gas or other waste heat. If the temperature of the water returning from the heat exchanger is no higher, or only barely higher, than that of the water flowing to it, the pump switches off, typically under the control of a low combustion gas temperature detector in the flue, and switching on again only if the maximum heat exchanger outlet temperature is exceeded. Specification printed 25.3.82.
